Application Notes

  • HDQ Communication Basics (Rev. A)
    PDF, 103 Kb, Revision: A, File published: Sep 18, 2008
    This report compares the communication timing specifications for the different battery gas gauge and battery monitor products. It discusses some of the interface requirements necessary for robust HDQ communication, such as the need for a break prior to each communication, how to reliably read 16-bit dynamic values over the 8-bit bus, and the need for some noise filtering on the HDQ line. It also
  • HDQ Communication Basics for TI Battery Monitor ICs
    PDF, 60 Kb, File published: May 16, 2001
    Most battery monitor ICs from TI, including the bq2018 and bq2019, includes a single-wire HDQ serial data interface. Host controllers, configured for either polled or interrupt processing, use the interface to access various IC registers. The purpose of this application note is to cover most of the communication related topics for these devices.
